Join the Friends of los Peñasquitos Canyon Preserve in surveying for and documenting the location of Monarch Butterflies, their caterpillars, and the milkweed plants they need.

Monarch populations have crashed all over the country. The decline of our Western populations has been dramatic according to recent surveys. This is a national effort from July 23 – August 1, 2021.

Hello all, as we did last year due to the heat, we’re pushing our start time to 3 PM. Dates for the coming 3 months are posted on our Event Calendar, our IG and Facebook pages.

This year the Coast to Crest Trail Challenge will include Lusardi Creek and Awhee Trail, on the west side of Black Mountain Open Space Park.
